# LaserMaster software notes

English pointers from the local cncu.co.za mirror (`T:\U\C\LaserMaster-Handheld-Laser-System`). **No pricing.** Software installers / ZIPs / MSI / APK / firmware binaries are **not** copied into this KB (URL + local path only). Copied English manuals live under `sources/manuals/lasermaster/` (`components/`, `software/`, `software/error-reset/`). Laser-source packages are in `drivers/lasermaster-firmware-index.md` (**6** packages; prefer Fiber Laser Management **V2.0.29**; binaries URL-only). **Newer wins.**
